Abstract

The current transformer arrangement on the secondary side with an integration stage is provided with a secondary winding consisting of two astatically designed coils (31, 32) lying next to one another and connected in series. As a result external parasitic magnetic fields have practically no effect on the transmission of the measured value. A large output signal from the secondary side is achieved by a large magnetic coupling of the primary conductor and secondary coil without the use of ferromagnetic materials. Preferably, the primary conductor (23) is designed as a flat conductor with suitably arranged slot-shaped recesses (25 to 28), so that primary windings (29a to 29g) are formed by changing the conductor cross-section (Fig. 5, 6, 7).
